====5.1.7.3 Bendability====
The measure for bendability of a strip material is the smallest possible bending radius r of a sample piece of given material thickness s without appearance of surface cracking. Bending tests are performed as either 90 degree bends according to ISO 7438 or as defined forth-and-back bending. The bendabilty of naturally hard copper alloys is significantly better perpendicular to the rolling direction than parallel to it [[#figures10|(Figs. 3 4 – 7)]](Figs. 5.41 and 5.42).
